Answer 1

the answer of this question is 122

Answer 2

Explanation :

Monoclinic crystalline structure : It is one of the 7 crystal systems. This crystal system is described by three vectors and these vectors are of unequal lengths.

The unequal lengths are a, b, and c where a is perpendicular to b and c, but b and c are not perpendicular to each other.  

And the angle between the edges that is, angle $\alpha$ between the edges b and c, angle $\beta$ between the edges a and c and angle $\gamma$ between the edges a and b.

The relation between these angles are, $\alpha=\gamma=90^o,\beta\neq 90^o$

The monoclinic crystalline structure is shown below.
